Wonder how Java open source projects use JetBrains IntelliJ?

Here are examples from:

Part 2 includes Selenide (among Spring, Play, Koin, Micronaut, OpenGrok, jsoup, http4k, Flix and Kobweb).

We are LIVE!!!! Go check out the NEW SITE, NEW GUIDE, NEW DOCS!! And then, when you’ve recovered from the awesomeness, go read the “V1 and Beyond” essay (much 🔥🌶️). Thank you to everyone who has contributed. It’s been an incredible journey getting here; now time to be boring!

[Datastar Cult Leader @DelaneyGillilan]

Highlights from @kotlinconf "We want to see more websites using Datastar". Thanks @http4k !

@razvanbunea @dmitrykandalov We're not sure about this for this event, but you can definitely see Full Stream ahead when it goes out at KotlinConf in May. And if you know of any other meetups which might be interested we'd love to hear about them! 🙃

Day 4 at #GITEXGlobal was packed with insights! 🌟 From learning about the #http4k protocol to key tips for AI startups, an engaging chat with Digital Einstein, a #DevOps presentation, and a roundtable on AI's future, so much to take in!

We had a nice reaction to the http4k IntelliJ plugin, so we decided to make it even better, by folding all of the http4k Toolbox functionality right into the IDE, including OpenAPI server generation, JSON to Dataclasses, and raw HTTP to http4k req. Available now inside IntelliJ

[http4k @http4k]

We're excited to announce that the http4k Project Wizard plugin is now available on the JetBrains Plugin Marketplace! With our shiny new plugin, setting up new http4k projects is now a complete breeze- direct from your IDE. Install direct from IntelliJ or https://t.co/uo2byrKzq1

🚀Today we're proud to launch a site for http4k Connect project: an entire http4k sub-ecosystem concentrating on the creation of modular API Client libraries. Supports many popular Cloud and AI services, or implement your own with the Connect pattern 🚀

Conceptually simple ✅
Tiny core ✅
Zero dependencies ✅
Makes people inexplicably mad ✅

HTMX truly is a library after our own ❤️ (and we do have a module for it 😉)

We'd considered poaching the CEO for our social media team, but they seem hard to pin down...

htmx mentioned!

great talk by Dan North https://t.co/zkYEDqDpP9 @kotlinconf

What if we build a web server just as a transformer of HttpRequests into HttpResponses?

Ooops, they already did it! @http4k

[http4k @http4k]

🌈 Even better than immediate feedback in Twitter - we'd love to arrange some calls so that we can meet your teams and chat to them to get as much info as we can. Drop your thoughts below or feel free to DM and we'll be in touch. 🫶

⭐️Hey everyone! ⭐️ 🎉As we continue to grow the http4k platform, we’d love to gather some insights from our users who are using the libraries at work.

Inspired by the talk at KotlinConf, we've released first class lens support for DataFrame in v5.21.2.0 of http4k. It's in maven now and you can see docs on using it here: https://t.co/Cs9oKqbqDT

@tyndyll @GarthGilmour @JetBrainsKtor @kotlinconf There was so much good content that there was no time for questions. 🙃
